Stabilizer Model: IEEEST

Following checks and corrections are applied during Validation and AutoCorrection.

• If 0.0 < T2 < 0.125*Mult*TimeStep then T2 = 0.0
  ElseIf 0.125*Mult*TimeStep < T2 < 0.25*Mult*TimeStep then T2 = 0.25*Mult*TimeStep
• If 0.0 < T4 < 0.125*Mult*TimeStep then T4 = 0.0
  ElseIf 0.125*Mult*TimeStep < T4 < 0.25*Mult*TimeStep then T4 = 0.25*Mult*TimeStep
• If 0 < T6 < Mult*TimeStep then T6 = Mult*TimeStep
• If Vcl < Vcu then swap the values
• If Lsmax < Lsmin then swap the values. If Lsmax < 0 then Lsmax change sign to positive. If Lsmin > 0 then change sign to negative.

Mult represents the user-specified value Minimum time constant size as multiple of time step option on the Validation page of the Transient Stability Dialog

TimeStep represents the integration time step being used as described on TimeStep
